Nice plants, Ento. I have a few in flower now, mostly of the Supertextae series, which is unusual for me. I moved house and until March 2017 the plants were in a dark garage (heated, just) but the new greenhouse has much better light than my old one. I think some of the plants are still adjusting to the new conditions because I haven't had flowers before in January. It's not been too cold here in the UK, but I keep the greenhouse at 5C at night, so now that it is about -3C overnight, they are comfortable.

Thanks, Chris. My greenhouses are not heated, the temperature was -1C only two days in December, January was not very cold. I leave the plants, from the end of October, to the dry, they will see the first water in the first days of April, temperature permitting. In these days it is raining and the temperature is around 3C at night. In the nearby hills the snow has fallen. I wait days with the sun to photograph other plants.

I have a yellow spines bombycina that came from Koehres seed. It was listed as bombycina Colomos. In 2010 on a field trip I saw this yellow spines form, and the next village we went through was Colomos!
